Emergency orthopaedic surgery in the pandemic era: A case series at Cipto Mangunkusumo national tertiary hospital in Jakarta, Indonesia.

INTRODUCTION: Every emergency surgery performed is aimed at saving lives; however, during COVID-19 pandemic, surgeries are often postponed. Many existing recommendations take into account postponing surgery during a pandemic. How these surgeries can lead to increasing infection rates has not been widely published. This study aims to investigate the relationship of emergency orthopaedic surgery and the incidence rate of COVID-19. PRESENTATION OF CASE: This was a case series of 14 patients. The study was performed at the emergency department unit at a national tertiary hospital in Jakarta, Indonesia. A total of 14 patients underwent orthopaedic surgery in the emergency room of our institution. The mean age of the subjects was 40.07 ± 20.5 years. Twelve (85.7%) were male patients and 2 (14.3%) were female patients. The average duration of surgery was 125 minutes. The most used type of anaesthesia was general anaesthesia for 6 operations (50%). Patients were hospitalized for an average length of 4 days. Three patients had infiltrates found on plain x-ray examination, which required further examination to determine whether the cause was COVID-19 infection or not. There was no ground glass appearance (GGO) in the three patients in further follow-up examination. CONCLUSIONS: We found that emergency orthopaedic surgery was not associated with increasing number of COVID-19 cases. Factors including duration of surgery, length of stay, types of anaesthesia and comorbidities were also not associated with COVID-19 cases in this study.

Clinical Outcome and Survival of Osteosarcoma Patients in Cipto Mangunkusumo Hospital: Limb Salvage Surgery versus Amputation.

AIM: to analyze the outcome and survival rate of osteosarcoma patients in our hospital as well as the factors affecting prognosis and functional outcome. METHODS: this is a retrospective cohort study of osteosarcoma patients in Cipto Mangunkusumo Hospital underwent limb salvage surgery (LSS), amputation, LSS + amputation, and refused surgery from year 1995 to 2014. The surgical decision was based on patient's age, staging, location, neurovascular involvement, Huvos type, functional demand, patient preference, and general condition. Functional outcome was assessed using the Musculoskeletal Tumor Society (MSTS) score with the maximum score of 30. RESULTS: subjects consisted of 80 male and 52 female aged 4 to 61 year-old. They underwent limb salvage surgery (LSS) (n=37), amputation (n=42), LSS + amputation (n=2), and refused surgery (n=51). Overall 5-year cumulative survival rate was 14.6%. The 5-year survival rate for each group; LSS, amputation, combined LSS and amputation, and refused surgery was 34.8%; 15.9%; 0%; and 0%, respectively. Patients with tumor size <8 cm tend to underwent LSS compared to amputations (60.7% vs 39.3%, p=0.046). Local recurrence-free survival for LSS and amputation was 96.2% and 86.5% respectively (p=0.586). MSTS score was higher in LSS than amputation group (25.0 vs 18.5, p=0.011). CONCLUSION: LSS had higher survival rate than amputation in osteosarcoma patients who were treated in Cipto Mangunkusumo Hospital. MSTS functional score in the LSS group was higher than amputation group.

Correlation between survival and tumour characteristics in patients with chondrosarcoma.

PURPOSE: To evaluate the correlation between survival and tumour characteristics in 23 patients with chondrosarcoma. METHODS: Records of 15 men and 8 women aged 14 to 66 (mean, 37) years who were diagnosed with primary (n=19) or secondary (n=4) chondrosarcoma of the axial skeleton (n=8), proximal extremity (n=9), or distal extremity (n=6) were reviewed. The tumour diameter was <10 cm in 4 patients, 10-19 cm in 12, and 20-30 cm in 7. The tumour involved the intramedullary in 17 and the periosteum in 6 patients; tumour extension was intracompartmental in 5 and extracompartmental in 18 patients. The Evans histological grade for the tumours was grade 1 in 6 patients, grade 2 in 10, and grade 3 in 7. The mean tumour size was 12.3 cm for grade 1 tumours, 18.2 cm for grade 2 tumours, and 18.3 cm for grade 3 tumours. 13 patients had no metastasis and 3 of 10 patients with grade 2 tumours and all 7 patients with grade 3 tumours had metastasis to the lung at presentation. 17 patients underwent surgery, one underwent adjuvant treatment only, and 5 declined treatment. RESULTS: The mean follow-up period for the 23 patients was 3.1 years (range, 3 weeks to 9 years). The 5-year survival rate was 43% overall, 83.3% for grade 1 tumours, 50% for grade 2 tumours, and 0% for grade 3 tumours. The median survival duration was 20 (95% confidence interval, 11-29) months. Two patients had local recurrence and 16 did not, and the 5 patients who declined treatment died. Survival correlated with Evans histological grading (p=0.004), the presence of metastasis at presentation (p=0.026) and local recurrence (p=0.004). CONCLUSION: The survival rate was lower in patients with higher Evan grading, metastasis, or local recurrence.

Lipoblastoma and lipoblastomatosis of the lower leg.

Lipoblastoma is a benign lesion of immature fat cells that is found almost exclusively in pediatric population. This tumor is a rare tumor that occurs in infancy and early childhood, accounting for less than 1% of all childhood neoplasm. It is more common in male than in female and often presents as an asymptomatic, rapidly enlarging, soft lobular mass on the extremity. Although benign, it gives great difficulty in its management, due to its extensions into different facial planes, especially in lipoblastomatosis. Thus, complete surgical excision is the treatment of choice.
